The footprint of bottom trawling in European waters: distribution, intensity, and seabed integrity [PDF]

, 2016
Mapping trawling pressure on the benthic habitats is needed as background to support an ecosystem approach to fisheries management (EAFM). The extent and intensity of bottom trawling on the European continental shelf (0–1000 m) was analyzed from logbook ...

Efficiency of the bottom trawl used for the Mediterranean International Trawl Survey (MEDITS) [PDF]

, 1999
The aim of the work presented in this paper was to assess the relative efficiency of the GOC 73 sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) compared with that of a typical Italian commercial trawl. The latter was chosen because it is commonly used by fishermen in the central Adriatic, where the experiment was

Trawling-Induced Sedimentary Dynamics in Submarine Canyons of the Gulf of Palermo (SW Mediterranean Sea)

Journal of Marine Science and Engineering
Bottom trawling in submarine canyons can affect their sedimentary dynamics, but studies addressing this topic are still scarce. In the Gulf of Palermo (NW Sicily, SW Mediterranean Sea), bottom trawling occurs on the continental slope, but principally ...

DEVELOPMENT AND TESTING OF ALGORITHM FOR CALCULATION OF OPERATING PARAMETERS OF TRAWLING SYSTEMS

Известия ТИНРО, 2019
Numerical model of trawling system is developed on the base of equilibrium principle, using F.I. Baranov’s scheme of its power and geometric parameters interdependence.

Effect of bottom trawling on physico-chemical parameters, benthos and fish fauna of Mangalore Coast, Karnataka State [PDF]

, 2012
Trawling, the most efficient method of catching fish world over is also found to be the most important human caused physical disturbance on the world's continental shelves and hence the physical destruction of ecosystems.Trawl gears often catch ...

A lightweight clear liquid optical chamber baited remote underwater video system for monitoring fish in turbid coastal wetlands

Limnology and Oceanography: Methods, EarlyView.
Abstract Clear liquid optical chamber baited remote underwater video systems (CLOC‐BRUV) are an effective option for assessing fish assemblages in turbid water, but current designs are limited by their large size and high operational costs. We developed a lightweight CLOC‐BRUV unit and evaluated its performance through proof‐of‐concept trials and field

Risk Assessment of Fishing Trawl Activities to Subsea Pipelines of Sabah and Labuan Waters

The Scientific World Journal, 2020
Introduction. Trawling is a method of catching fish in a large volume where fish nets are pulled through water using one or two boats. Bottom trawling is where the nets are pulled over on the seabed.

Organic matter contents and degradation in a highly trawled area during fresh particle inputs (Gulf of Castellammare, southwestern Mediterranean) [PDF]

Biogeosciences, 2019
Bottom trawling in the deep sea is one of the main drivers of sediment resuspension, eroding the seafloor and altering the content and composition of sedimentary organic matter (OM). The physical and biogeochemical impacts of bottom trawling were studied

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

Limnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Density Dependent Catchability In Bottom Trawl Surveys

, 1997
No abstracts are to be cited without prior reference to the author.Fish form schools, layer or patches in which the individual fish's behaviour is not independent ofits neighbours movements. On the other hand, at low densities fish may have the freedom to actas single individuals independently of what other fish are doing.
